Hi Ken,
May or may not be a related topic, but thought my following info might help
you long term.
I had been using a filter I built on my phone line that feeds my DSL modem
(original filter design by OZ1CTK), and this stopped the continuous crashes
of my ADSL modem. Well after many years my ADSL modem finally failed and
ATT sent me a new ADSL modem (different model) which also has WIFI built
in. The new modem would crash as soon as I transmitted on 160 meters, so I
added filtering to the 117 volt line cored (identical to what I recently
posted for my treadmill filtering), and this immediately fixed my
problems. I did this at the last minute as I was one of the W1AW/9
stations so did not have time to figure out exactly which filters were
really required (they cured my problem during a very critical time, and
that is all that mattered).
Bottom line is that I now have filtering on the phone line that comes into
the DSL modem, a toroid choke on the 117 volt line cored for common mode
suppression, and a commercially purchased line filter (made by Delta) that
provides both common mode and differential mode filtering, and my new ADSL
modem no longer crashes.
Just FYI,
Don (wd8dsb)
